- addition to such an extent that the known steering devices prove insuflicient for perfectly accurate steering, especially upon hilly or inclined ground, since they do not allow the adjustment of the pole in any desired inclination to the longitudinal direction of the cultivator in order to cause the draft animals to go always in the furrows or in the center between the plant rows. The laterally extending steering devices provided on the known machinesare rigidly connected with the frame, and where a steering device for steering from the rear exiets, it consists nearly always of several parts.

1 According to the present invention, a rod attached by means of a. ll-shaped angular support and a spring pressed catch to a recessed disk may be rotated upon this latter, this rod being also longitudinally slidable, after a set screw has been unscrewed; said rod may be adjusted in any desired angle with respect to the cultivator, being then employed either as a pole for the same, or for steering the machine from the rear, or serving, if it is afiixed at its center part, for steering the machine from the. side. To allow of adjusting the front end of the pole vertically as desired with regard to the position of the fulcrum, if such adjustment should become necessary, the supports of the recessed disk are pivotally attached by means of supporting screws, to the vertical front frame bar. To allow of employing this arrangement also in connection with a one-horse cultivator, a thill may be pivotally connected to the poleor thill-carrier by.

means of a cross-bar, and in a similar way also a one-wheeled front frame may be made use of, 1n connectlon with the double U- shaped supporting girders, preferably in with a guide-pivot extending to the drafthook, is exchanged for a bow within which one of the two front wheels is arranged by meansof a supporting pivot.

In order to make my invention more clear, I refer to the accompanying drawings, in which similar numerals denote similar parts throughout the several views, and in which:

Figure 1 is a front view of the front frame, a part of the bar 1 being broken away and the pole 6 being shown in section; Fig. 2 is a side view of the parts shown in the upper half of Fig. 1 Fig. 3 is a plan of. the parts shown in the upper half of Fig. 2; Fig. 4 is a view similar to Fig. 2, showing a slightly modified form of construction; Fig. 5 is a similar representation showing the lower parts of Fig. i turned in an angl of 90; Fig. 6 is a representationsimilar to Fig. 3,,drawn on a smaller scale and show ing the recessed disk combined with a thill; and lfiig. 1s a side view of the parts shown 1n F 1g. 6. Figs. 8 and 9 are side views of a cultivator constructed according to the pres-' ent invention.

Referring to Figs. 1-3 the vertical bar 1, which is rigidly secured to thecenter part of the front frame, has affixed to its upper end a U-shaped bow 2, which is connected with a disk 3 cooperating with a springpressed catch I attached to a supporting bar 5 which is pivoted at 7 to the center of said recessed disk and is provided with means for being coupled with the pole 6 which thus may be laterally turned into any position with respect to the disk 3 and may be secured in that position by the catch 4-.

In the form of construction shown in Figs. l and 5 the bow 2 is replaced by two augularly bent bars 10 which are connected.

with the bar 1 by means of a bolt 8 upon which the bars may be turned so as to bring the disk 3 and the other upper parts. including the pole 6, into an inclined position. In other words: the pole 6 can be adjusted not only horizontally but also vertically. The lower ends of the bars 10 are broadened and have each a slot 11 through which extends a bolt 9 also supported by the bar 1. This bolt serves for securing the bars 10 in their position after adjustment.

In the form of construction shown in Figs. 6 and 7 which is intended for a onehorse machine, the thill 12 is attached by means of a cross bar 13 to the sleeve 14 which forms the front end of the thill holder 15. This latter may be at liberty connected with or disconnected from the recessed disk, that is to say,,it may be re placed, if desired or necessary, by a pole as required for a two-horse machine or cultivator respectively. In a similar manner, the twowheeled front frame customary with cultivators may be exchanged for a onewheeled one as shown in Fig. 1. This is effected in a very simple manner by merely siibsti tirti ngi the bow 16 for-the couriterrflate of the front frame bar lg'the said bow "servthat Fig. 4 shows the pole arranged as a draft part, Whereas Fig. 5 ployed as hand bar.

The operation of the device willbecome apparent from Figs. 8 and 9 which show the pole 6 in its normal position and indicatein Fig. 9 in dotted lines its position for use as a hand steering "device where it is displaced in its bearing 5 in such a manner that it comes Within reach of the handles arrangedat the cultivator frame. The pole is guided over the seed box and is adjusted by means of the screws 8 and 11 in inclined position.v

Having now described my invention, what shows it em- I desire to secure by Letters Patent of the 'UnitedStates is: I

1. In a front frame for cultivators, the combinatlon, with a recessed disk secured to the vertical front frame bar, of a pole or 'and the holder in any desired position of the latter.

2. In a front frame for cultivators, the combination, with a recessed disk secured to the Vertical front frame bar, ofa pole-holder adapted to be turned upon the same; a pole arranged in said holder and adapted to 'be displaced in the same; and a spring pressed catch for coupling the disk and the holder with the pole in any position of this latter.

3. In a front frame for cultivators, the combination, with a recessed disk, supports for the same, a front frame bar holding said supports; of a pole-holder attached to the center of said disk, a bolt held by said bar and serving as fulcrum for the support slots in the lower ends 'of the latter; another bolt (also held by the front frame bar and extending through said slots; and a spring pressed catch for coupling the disk and the holder in any desired position.

In testimony whereof I aflix my signature in presence of two witnesses.
